The rocky coast biome would be a biome about 900 blocks long and wide, consisting of blocks like cobble, sand, and a new block: spiny rock. Spiny rocks would build up in clusters and they would be as tall as an iron golem. Like cacti, if you touch them, you will get hurt. If you’re able to break it (using an iron pickaxe) you can put it in water, and after a while in there, you will see bubbles sizzling on the water, and then you would hear a pop! This means that the spiny rock’s spikes have come off. Anyways, a few new mobs ideas I was thinking about were frigate bird, barnacles, Blue footed booby, and hermit crab. The frigate bird (6 health) would attack blue footed boobies ( 5 health) if they caught cod, and they would also attack players if they went too close to their nest. You could feed frigate birds and blue footed boobies fish or soft rock spikes. Barnacles (as big as a baby turtle and 1 heart) would once in a while poke out of it’s shell, but only would be able to stay in one place( able to spawn on the side of rocks too) if you find a colony of about 10 in each, you would have to sneak so you wouldn’t step on them. And the last animal, is the hermit crab( 9 hearts; about as big as a vex) if you started sprinting towards them, they would hide in their shells and if you broke the shell, they would try to pinch you, taking away 2 hearts every time. One other things i’d like to add is tide pools and/ or old trees filled with frogs.I’m so happy about this idea!
